This research was conducted to design a prototype of a wireless electrical energy transmission system and design a wireless electrical energy recording system using the NRF24L01 wireless transmitter module and the PZEM004T kWh meter module. The design in this study uses the principle of electromagnetic induction to transfer electrical energy at close range, while to transmit data, the authors use the NRF24L01 module. Besides, the authors use the PZEM004T module to measure various magnitudes. Based on the results of observations and measurements of the design of the tool, the authors found that the transmission of electrical energy using electromagnetic induction is not effective for longer distances because the energy lost in the air is getting bigger. So this technology needs to be further investigated. Besides, the measurement of electrical quantities using the PZEM module has a small difference (under 2%) with measurements using a multimeter, so it can be said that the measurement with the PZEM004T module is effective. </span></span>

Customer churn factors detection in Indonesian postpaid telecommunication services as a supporting medium for preventing waste of IT components

One of the most important tasks in the telecommunication company is to maintain the customer churn rate and customer satisfaction level. These things can be maintained by evaluating the churn customer factors. The results of this evaluation can certainly be used to improve the services of the company, so that customers will be stopped from churn and customer satisfaction level will be increased. This condition indirectly provided positive effect on the environment by preventing e-waste of IT components. In this research study, customer churn factors from customer feedback were evaluated by using text mining, by targeting the postpaid customers in one of telecommunication company in Indonesia. In this research we used 3 classification methodology, Fast Large-Margin, Naïve Bayes, and Support Vector Machine. Fast Large-Margin classification methodology was the most accurate model in this research, was used to classify the customer feedback for five following customer churn factors in telecommunication industry: poor customer service, poor network, high cost of services, billing errors, and promotion seeking. The result shows that promotion seeking was the most factor that caused customer to churn during January and December 2019 period.

The Ban of Off-Net/On-Net Price Discrimination in Chile†

Abstract Chilean antitrust authorities banned termination-based price discrimination in mobile calls in 2012. This paper discusses the antitrust process that led to this prohibition and analyzes its merits. We characterize the discriminatory plans that the largest mobile company in Chile—Movistar—offered in 2010, when the legal dispute began, calibrate a competition model for the Chilean market—both for pre- and post-paid customers—and compare the observed price differentials with those which are justifiable on competitive grounds. The main result is that in most plans, efficiency and strategic reasons could explain the observed differential only for large call externality parameter values. We also discuss Competition Court rulings in the context of several other changes that affected the mobile telephony market in Chile and report the evolution of several key market indicators after the ban was introduced.

Churn Analysis in a Romanian Telecommunications Company

Telecommunications is one of the sectors where the customer base plays a significant role in maintaining stable revenues, so special attention is paid to prevent their migration to other providers. Over time, businesses in the telecommunications industry have faced multiple threats of financial loss from migrating customers who want to leave their telecom service provider in exchange for other offers from competing companies. An effective prediction model of this action can not only be viewed as an insurance policy, supporting stable revenue, but also provides suggestions for database management so that potential migrant customers can benefit from personalized offers and services, depending on their profile, thus preventing their loss. The aim of this paper is to predict customers who are going to defect in a Romanian mobile telecommunications company. The churn analysis is developed for post-paid customers. We used logistic regression to predict churn and a solution based on smoothed bootstrap technique to correct for the drawbacks of imbalanced classes. In our study this procedure did not significantly improve the performance of the logistic classifier measured by AUC (Area Under the Receiver Operating Characteristic curve). So even after balancing the sample we still obtain a really reduced value of the AUC, making it difficult to correctly predict churn phenomenon on the available data set.

Two Samples Of Enviromental And Green Procurement At Turkcell

Green Procurement means purchasing products and services that cause minimal adverse environmental impacts. It incorporates human health and environmental concerns into the search for high quality products and services at competitive prices. [1]This study shows 2 examples of Sustainable and Green Procurement & Supply at Turkcell, the number one digital telecommunication company of the world where its headquarter is in Istanbul, Turkey. These examples are shown below:First: Turkcell has started a compost project that enabled to transform daily 140 kg of its food wastes into soil at headquarter in Istanbul, Turkey.Second: In May 2018 Turkcell reached its main goal of “95% green invoice production”. Its supplier prints & sends to only 1.1 millions of the customers their physical invoices (5% of total postpaid customers); remaining 20.9 milions receive their invoices by e-mail and SMS without using physical papers.

Termination notice of mobile network operator customers after a tariff switch: An empirical study of postpaid subscribers in Germany

Proactive subscriber churn management strategies of mobile network operators (MNOs) require that steps are taken to keep customers before they hand over a formal notice of termination to their provider. Therefore, several studies have analyzed how MNO customers who gave a termination announcement differ from individuals who did not communicate this message. However, no work has examined such differences among subscribers who recently switched to another tariff of their MNO. Therefore, this paper explores socio-demographic, service consumption and tariff change differences between contract cancellation “announcers” and “non-announcers” in a sample of 1810 postpaid customers who had changed their rate plan not long ago. Cancellation announcers were more likely to be males who decreased their mobile voice consumption after their tariff switch, had already attempted to churn in the past, had moved from an unmetered to a metered rate type, paid higher monthly bill amounts and received no discounts on their current rate plan that was introduced on the market some time ago. Among subscribers who gave a termination notice, early (late) cancellation announcers were more likely to be older (younger) customers with a growing (shrinking) SMS consumption after their tariff switch, had not attempted (had already tried) to leave their current MNO in the past, and were in a rate plan that was (not) recently introduced. The findings contribute to the literature on mobile customer retention and have implications for practitioners and scholars.

Exploring switching factors for mobile number portability: A survey

Pakistan’s mobile phone market is one of the world’s fastest growing markets with a subscriber base of 137 million users. Competition in the country’s telecommunication industry is dominated by four players and customer demand is high. In addition, Pakistan is the first country in South Asia to have implemented Mobile Number Portability (MNP) in March 2007. MNP is a facility that allows mobile subscribers to switch between service providers without changing their existing phone numbers. Mobile phone service provider’s selection may be influenced by various factors. Therefore, this research was undertaken to explore factors affecting MNP and to determine which factors were most influential in the selection of mobile phone service providers in a developing economy like Pakistan. Moreover, the study also probed into differences in customer perceptions between pre-paid and post-paid customers. This exploratory study is based on primary data collected from 300 customers using services of different cellular companies who had experienced MNP facility. Factor analysis was carried out on obtained data and reliability of the resultant scale was verified to achieve the objectives of the study. The outcome of this research provided a concise framework of the various dimensions of customer choice. Contrary to previous researches, the result of this study indicated that infrastructural services, customer relationships, call quality and promotional packages were the most important factors affecting MNP. However, price of services was found less important factor in selection of telecommunication service providers. This study also showed that pre-paid and post-paid customers can be significantly different for many value-added services and promotional tools.

Assessing the consumers’ willingness to adopt a prepayment metering system in Nigeria

Despite the rising popularity in the adoption and usage of prepayment meters, little is still known about the drivers of its adoption. We examine the willingness to adopt prepayment metering (PPM) for a sample of Nigerian households that were not prepayment users. Double-hurdle models were estimated to account for households’ decisions concerning billing system switching behaviour and households’ willingness to pay (WTP). The estimated results revealed that decisions to adopt a prepayment meter are significantly affected by current electricity spending, current billing method and the split incentive problem. Whereas current electricity spending significantly increased the tendency to adopt PPM, the split incentive problem reduced the probability of adoption. Although unmetered consumers were more likely to express a willingness to adopt a PPM system than post-paid customers, they did not intend to pay a significantly higher amount to obtain the prepayment service. Income did not play a significant role in decision-making concerning PPM adoption and the corresponding WTP amount. These results cast doubt on the validity of the widely held belief that low income may be responsible for PPM adoption, reflecting the widespread usage of PPM by low-income households.

Who is (not) convinced to withdraw a contract termination announcement? – A discriminant analysis of mobile communications customers in Germany

Convincing subscribers of mobile network operators (MNOs), who announce to terminate their contract at the next legally possible occasion to revoke their notice, is a challenge in the maturing MNO service industry. Using data for 607,948 postpaid customers of the German subsidiary of a multinational MNO, this study explores differences in contract-related, socio-demographic and service use behavior characteristics as well as in the stated primary cancellation reason between three subscriber groups: (1) customers withdrawing their termination and accepting a follow-up contract (full restoration group; n=276,488); (2) customers not revoking the cancellation of their postpaid contract, but accepting a prepaid offer of their MNO (partial restoration group; n=40,500); (3) churning customers sticking to their cancellation (loss group; n=290,960). The data reveal that compared to defecting customers, subscribers in the full restoration group were more likely (a) to try to cancel their agreement as a precautionary measure, (b) to be already in a tariff bundling mobile Internet and voice calling service provisioning, (c) to have a shorter overall length of contract relationship with their MNO and (d) to generate higher monthly revenues. Lost subscribers were much less inclined to name any reason at all for their defection notice than the two remaining groups. The share of subjects stating that a mismatch between their personal communication needs and their postpaid arrangement was the main driver to quit, was significantly higher in the partially restored group than in the rest of the sample. Overall, the characteristics of partially restored accounts were more similar to lost than to fully restored subscribers. Implications of the findings are discussed for regulators and customer restoration efforts of MNOs.

Estimating cellphone providers' customer equity

This paper provides insights about how customer equity estimates can help businesses monitor the competition as well as aid managers in making their marketing investment decisions, and how companies can employ their marketing investments to maximize current and future yield/returns. The article concerns itself with the current offer of cellphone providers and their main products. The research includes survey data through interviews with 302 cellphone users of Sao Paulo, Brazil. The study uses this data combined with a number of economic assumptions and a financial marketing model to create an insight in customer equity values of cellphone providers in the region. The scenario dated October 2005 is that the estimated customer equity of the service provider Vivo is, respectively, 93 and 91% larger than those of competing providers Claro and TIM. The research underlines that on average the customer equity flowing from the post-paid segment is 3.5 times larger than that of the pre-paid. In addition to these results the study provides the customer lifetime value (CLV) estimates for Claro's, TIM's and Vivo's pre- and post-paid customers and analyzes the retention and loss figures of CLV. Also a discussion follows of the implications that these values will likely have for the companies' marketing strategy.
